THOUSANDS of cars in the lots and you think you can stop them?? You've got to be kidding!
who said Stop. Did I say STOP? Don't put words in my mouth. Nobody said stop. But you would greatly reduce the problem. Have security walk through the lots and just keep an eye out. Anyone who is caught drinking booze in a team owned lot, gets their parking pass revoked and possible loss of season tickets. Of course some people will beat the system and cheat it and get around it. BUT ON A WHOLE it reduces the number of drunks at least on "team owned" property prior to the game by a lot. Goes a long way in getting the problem under control.
And not EVERY ONE of those "thousands of cars" tailgate...another silly leap you made
